I have a good friend that I have known for a few years. She went through a hard time with a break up about a year ago and was really down. I supported her through this, offered to meet up regularly to try perk her up which we did frequently, sat in the park together when we could during lockdown and she would open up to me, text her almost every day and listened to her struggles. I started getting health problems around this time and she told me to get in contact with her if I ever need help with anything. A few months later she seemed to started feeling better about everything, and we've kept messaging quite frequently but the phonecalls and the meeting up has more or less stopped. She's been seemingly ok for the past 6 months ish.
My general health has declined further and I've been under investigation for it for a number of months. They're not sure what is going on, but are thinking maybe something autoimmune. It's been quite a hard thing for me to deal with, and I tried to confide in my friend and she's having none of it. Infact, I opened up via text just over a month ago about how hard this has all been for me and how I'm struggling and asked if we can meet up or jump on a call. She kept saying she's busy, and a few days later we had a bit of an disagreement about it, where she was saying she's got a lot on and it's unfair that I'm offloading on to her when she doesn't have the headspace to deal with it. I explained I was just hoping for a phone call and she said she will call me when she has time.
Well, it's a month later, and not only has she not called, the texts have gone from multiple times a week to once a week or two. I've concluded she's probably distancing herself from me. I asked her if she's doing ok and she said she's fine.
I can't help but feel seriously hurt by all this and a bit of an idiot. I feel like I've been taken advantage of and given her all the support though her struggles and she's not willing to support me in the slightest when I've been going through hard times. She's told me it's unfair that I expect her to be there for me when she's got her own things going on (I don't know what these things are, I assumed if she wanted to tell me she would, but she hasn't gone into any detail)
My gut is telling me to end the friendship. The complete lack of support from her has added more upset to an already upsetting situation. I want to tell her how much shes let me down and ask her not to message me again. The most frustrating thing is I feel like she wouldn't really give a crap and I'll be the one sat here grieving the end of a friendship as I'm the one at the moment who could really do with the support.
I do wonder if I'm being unreasonable and it isn't her job to support me and maybe I'm being too sensitive about this. I also wonder whether she's going through something very difficult too like she's alluded to but hasn't told me the details. I don't expect her to share everything but I'm finding it hard to sympathise when I have zero idea what's going on if there is something wrong. At the moment it feels like she's making excuses to not have to deal with me.
AIBU if I formally end the friendship?
